Spacewalking astronauts gave a hand to the International Space Station’s big robot arm today.
As the federal government geared back up 250 miles below, NASA astronauts Mark Vande Hei and Scott Tingle floated outdoors to install the new mechanical gripper.
Because of the lingering effects of the government shutdown, the spacewalk got started in the morning without live coverage on NASA TV.
